Need help to solve this

Step-by-step explanation:

in a right triangle,

c^2=a^2+b^2

c^2=18^+15^2=324+225=549

c=sqrt549=23.50

The answer should be 23.4

Step-by-step explanation:

I attached my note to see if that help

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
